Patent DE-3202058-A1 (DE)
Title: Structural member, consisting of an air-tight and vapour-tight, solid covering which encloses a hollow space with inserted, expanding filling material
Inventor: BECKER OTTO ALFRED DR
IPC: E04C3/29
Filed: 1982-01-23
Abstract: Described as an exemplary embodiment is, inter alia, the use of the expanding filling materials for bridge construction. The hollow space of the structural members is subdivided by transverse walls into individual chambers. The chamber walls are alternately arranged at oppositely directed prestressing spindles in such a way that the poured-in, expanding prestressing material presses towards the free spindle end. In this way, the spindles, running in opposite directions, are tensioned in opposite directions. Prestressing arches can also be arranged, the ends of the arches being welded to that spindle whose free end points in the same direction as the welded-on end of the prestressing arch. Additionally, prestressing devices are arranged at least for the free spindle ends resting in the abutments. By prestressing tubes concentrically combined with one another, the expansion force of each filling space can be added without limit to that of the filling space situated to the inside and thus a central spindle can be prestressed up to the breaking limit (see Fig. 14). In addition, the invention permits further highly significant applications. This also applies in general to buildings, construction machines, cranes, turbines, ships, aircraft and other constructions as well as for the driving of machines. To facilitate understanding, Figure 15 (bridge construction) is attached. <IMAGE>

Patent DE-3222549-A1 (DE)
Title: Process and apparatus for fastening retaining claws for matched boards and strips
Inventor: WILLENBROCK HANS DIPL ING
IPC: E04F13/08
Filed: 1982-06-16
Abstract: The invention relates to a process and apparatus for fastening retaining claws, for example retaining claws for matched boards, by means of U-shaped clamps which are driven into a base surface. To increase the extraction resistance of the clamps, in particular those with small cross-sections, it is desirable to deform, for example to bend, the clamps when driving them into the base surface. This is achieved according to the invention by the legs of the clamps being guided along deflection elements during driving-in. These deflection elements can be provided in pairs on the retaining claws.

Title: Circuit arrangement for maximum utilisation of arithmetic units in time-slice-controlled multiprogram processing
Inventor: EBERT RAINER DIPL ING
IPC: G06F9/48
Filed: 1982-06-25
Abstract: The invention relates to a circuit arrangement for maximum utilisation of the available time in the time-slice-controlled simultaneous processing of several programs in a computer system. The invention has the purpose of achieving maximum utilisation of the time available to an arithmetic unit in the simultaneous processing of several tasks or programs. It is the object of the invention to create a circuit arrangement for an arithmetic unit, operating in real-time mode, with time-slice control for the simultaneous processing of several programs, which enables computing time to be allocated in dependence on the current program states. This object is achieved by a real-time system control for sequentially correct allocation of the time slices to the processing modules. The real-time system control contains a priority comparator which effects the switching-over of the arithmetic unit after a constant time interval within each time slice to the module with the highest priority at this instant. After the time slice has elapsed, work is continued in the order of the priority chain.
Patent DE-3227366-A1 (DE)
Title: Film tear-off block for the visor of crash helmets
Inventor: BISCHOFF HANS PETER
IPC: A42B3/26
Filed: 1982-07-22
Abstract: It consists of a plurality of superimposed, thin, very transparent plastic films which are assembled at both ends so as to be easily detachable, for example by self-adhesion or corrugating, and are dimensioned such that they extend over the visor of the crash helmet. The lowermost film has at both ends self-adhesive strips with which the block can be fastened to the visor. The individual films have a detachment point at both ends, with which they can be easily grasped and peeled off. As soon as one film is soiled by insects during driving, that is to say vision is impaired, it is peeled off and the next, clean film follows and restores the good visual protection of the visor. The films can be, for example, white, special sea-green colour, smoke-grey or super-black colour. An individual film can of course be used instead of the block.

Title: Steel melting plant with two furnace vessels
Inventor: DIKTA GERD DIPL ING
IPC: F27B3/04
Filed: 1982-08-26
Abstract: The invention relates to a steel melting plant having two stationary furnace vessels arranged on a furnace platform, especially for melting scrap, and having interchangeable vessel covers, one of which carries the heating device (electrodes), the melting process taking place alternately in the first or second vessel while the material to be melted is prepared in the other vessel. In order to design a steel melting plant of the type described at the beginning, in such a way that the duct for removal of the exhaust gases does not come into contact with the melt or melt splashes, and in addition opens into the respective other furnace vessel such that the heat of the exhaust gases can be optimally used, it is proposed that a suction bend which can be connected to a gas duct be arranged on each cover, that the gas duct opens in each case into the lower casing region of the other vessel, and a secondary duct leading to a dust removal device be branched from each gas duct, and that a gas shut-off valve be arranged in the gas duct, in the gas flow direction, behind the branch point of the secondary duct and, to prevent charged or molten material leaving the furnace, a closure device be arranged in the opening of the gas duct into the furnace. <IMAGE>
Patent DE-3233473-A1 (DE)
Title: Thermoelectric plant with "gas/steam cycle" for the complete conversion of heat into mechanical work
Inventor: GENSWEIN ALFONS DIPL ING
IPC: F01K21/00
Filed: 1982-09-09
Abstract: A thermoelectric plant with a so-called "gas/steam cycle" is proposed which is operated between the overheated and saturated to dry saturated state of a superheated or cold steam and consequently avoids the constant heating and evaporation of the feed liquid by means of the boiler or evaporator. The return of the wet steam (X APPROX  0.9) can therefore be carried out with normal turbocompressors or piston-type machines (Figs. 1 and 1.1). The cycle passes through the following states (Figs. 2-3, shown for simple overheating): 1)Isobaric heat absorption from the dew point to far into the overheating region (gaseous state): state 1 -> 2, 2)adiabatic/isentropic expansion into the saturation state (X  APPROX  0.9) with  kappa  = 1.3, with work being performed: state 2 -> 3, 3)adiabatic/isentropic compression of the wet steam with  kappa  = 1.135 with work being expended and, consequently, completion of the cycle: state 3 -> 1. The area enclosed between the three states in the pressure/volume diagram (Fig. 2) is equal to the differential work Weff from the two work processes; it is equivalent to the heat qu absorbed on the primary side. The thermal efficiency of the plant (expansion plus compression machine) is consequently 100% and therefore independent of the thermodynamic temperature drop present in each case. The useful heat area can be increased by high temperatures and repeated intermediate overheating and the useful work ratio (work of expansion/work of compression) of the plant can consequently be increased (Figs. 4 and 5).

Title: Process for continuously producing plaster-bound panels, and device for carrying out the process
Inventor: BUECKING GUENTER
IPC: B28B1/52
Filed: 1982-12-18
Abstract: The process serves for continuously producing plaster-bound panels, in which lignocellulose-containing and/or cellulose-containing and/or inorganic particles, which contain the setting water for the gypsum are fed in a form mixed with the pulverulent gypsum to a moving substrate to form a mat which is then pressed to give a string of panels. In this process, the setting water is first added to the particles and the gypsum to the particles - or vice versa - immediately before mixing. The blend of gypsum and the particles thus formed is homogeneously mixed along the dropping path onto the substrate and, by means of pouring, drops substantially vertically onto the substrate, the mat thus being formed being pressed at a controlled temperature.

Title: Method and device for testing the permeability of membrane filters
Inventor: HOFMANN FRIEDER DR
IPC: G01N15/08
Filed: 1982-12-27
Abstract: In the method and the device for testing the permeability of membrane filters, the moistened membrane filter is exposed to a predetermined test-gas pressure on the feed side in a first closed system and the pressure change in the closed system with time is measured. In the test methods hitherto known, the pressure at which the diffusion-gas stream became a combined diffusion- and conduction-gas stream through the membrane to be tested could be determined only inaccurately and with difficulty. The object of the invention is a more sensitive test method with which the permeability and, consequently, the pore size of a membrane filter can be determined solely from measurements on the feed side of the membrane filter. This is achieved by bringing a reference-pressure system to the test-gas pressure at the beginning of every measurement and by measuring the pressure change in the form of the pressure difference between the first system and the reference-pressure system.

Title: Closing device for the exhaust system of an internal-combustion engine
Inventor: SCHLEGL EUGEN ING GRAD
IPC: F01N13/08
Filed: 1983-10-11
Abstract: A closing device for the exhaust system of the internal-combustion engine of a submersible or amphibious vehicle has in the exhaust duct of the exhaust system a spring-loaded closing flap, by which the exhaust duct can be closed automatically when the exhaust pressure subsides and the internal-combustion engine is switched off. Upstream of the closure flap in the exhaust duct there is a drainage orifice which opens out into an engine space and through which leakage water getting in through the closure flap in the submerged state can be led away out of the exhaust duct. In order to prevent the engine space being subjected constantly to exhaust gas during normal operation and to ensure that, when starting, the exhaust gas can expand without any great restricting effect via the drainage orifice into the engine space, the drainage orifice can be closed by a positively controlled drainage flap.

Patent DE-3338026-A1 (DE)
Title: Optical cable
Inventor: SMITH JOHN CARSWELL
IPC: G02B6/44
Filed: 1983-10-20
Abstract: In the novel optical cable (1), a corrugated strip (15) is wound overlapped around a central stress-relieving element (11). Optical waveguides (21) are situated in the grooves (17) of the corrugated strip (15). The depth of the grooves suffices to accommodate one or more optical waveguides. The corrugated strip (15) is surrounded by a protective cladding (23, 25, 27). By combining a plurality of these optical cables (1), it is possible to form a cable having a multiplicity of optical waveguides which has an external cladding. The method for producing such an optical cable has as an essential method step that the central stress-relieving element is twisted on being pulled off from a supply reel. Laid hereover with the aid of a compression mould is the corrugated strip, so that the grooves of the corrugated strip are wound on spirally. <IMAGE>
